Hello fellow vets and active duty, I am a retired Marine. Retired March 2013 after 20. Semper Fi I'm seeking assistance with a question. I currently have a disability rating with the VA (previous VA claim). Within 60 days of my retirement I had heart failure and had to get a pace maker and soon thereafter another surgical procedure on my heart. I am currently on meds to keep my heart working along with the pace maker. Not to mention anxiety medication. I am seeking advice on submitting another VA claim. Is it too late? From what I have read so far it has to be within a year. Is that true? I really appreciate any advice that you guys could offer me. Thank you Jason SSgt, USMC (ret)
